Cautions in Using with Safety
Fundamental Matters of “WARNING!” and “CAUTION!”
WARNING!
Do not use this unit in an area where there is flammable or explosive gas
Never use this unit in an area where there is flammable or explosive gas.
This unit is not explosion-proof. An arc may be generated when the power switch is turned on or off,
and fire/explosion may result. (Refer to page22 “List of Dangerous Substances”.)
Always ground this unit
Always ground this unit on the power equipment side in order to avoid electrical shock due to a power
surge.
If a problem occurs
If smoke or strange odor should come out of this unit for some reason, turn off the power key right
away, and then turn off the circuit breaker and the main power. Immediately contact a service
technician for inspection. If this procedure is not followed, fire or electrical shock may result. Never
perform repair work yourself, since it is dangerous and not recommended.
Do not use the power cord if it is bundled or tangled
Do not use the power cord if it is bundled or tangled. If it is used in this manner, it can overheat and
fire may be caused.
Do not process, bend, wring, or stretch the power cord forcibly
Do not process, bend, wring, or stretch the power cord forcibly. Fire or electrical shock may result.
Pay special attention to the measure for flammability
and handling of flammable solvent
Leaving at the temperature higher than the room temperature may vaporize the flammable material
(ethanol, etc.). There might be the case that some flammable liquid might be vaporized at the
temperature lower than the room temperature. The result of such careless handling could cause the
fire or explosion. Do provide the vaporization with enough during the operation.
Do not disassemble or modify this unit
Do not disassemble or modify this unit. Fire or electrical shock or failure may be caused.

Cautions in Using with Safety
Fundamental Matters of “WARNING!” and “CAUTION!”
CAUTION!
During a thunder storm
During a thunderstorm, turn off the power key immediately, then turn off the circuit breaker and the main
power. If this procedure is not followed, fire or electrical shock may be caused.
Do not touch the condensed liquid in the cooling coil and trap bath
Since the condensed liquid in the cooling coil and trap bath is stayed with low temperature, never touch
it so as to preventing from getting frostbite on your hands.
Do not touch the cooling fin with bare hands
Do not touch the cooling fin with bare hands during maintenance, for the edge of the cooling fin is too
sharp to cut your hand.

♦ Rough or dirty surface.
♦ Flammable gas or corrosive gas is generated.
♦ Ambient temperature bellow 5℃ or above 35°C. (CA300)
♦ Ambient temperature bellow 5℃ or above 30°C. (CA800)
♦ Ambient temperature fluctuates violently.
♦ There is direct sunlight.
♦ There is excessive humidity and dust.
♦ There is a constant vibration.
• Install this unit on a stable place with the space as shown below.
More than
20cm
More than
20cm
Front side
More than 40cm
3. Do not use this unit in an area where there is flammable or explosive gas
• Never use this unit in an area where there is
flammable or explosive gas. This unit is not
explosion-proof. An arc may be generated

Before Using this unit
Requirements for Installation
CAUTION!
6. Use specified receptacle for power source
• Choose a correct power distribution board or receptacle that meets the unit’s rated electric
capacity.
Electric capacity: CA300: 100V AC, 50/60Hz, 6A
CA800: 100V AC, 50/60Hz, 10A
NOTE)
Starburst connection with a branching receptacle or extended wiring with a cord reel lowers
electrical power voltage, which may cause the degradation of refrigeration capability.
7. Before/after installing
• It may cause injure to a person if this unit falls down or moves by the earthquake and the
impact. etc..To prevent, take measures that the unit cannot fall down, and not install to busy
place.
• Though this unit has the air-cooled refrigerator, the device exhausts the heat. Do provide the
vaporization with enough so as not to raise the ambient temperature caused by the exhaust of
the heat, or install this unit with its air controlled completely. If the ambient temperature
becomes high, the operation efficiency becomes worse, and could cause the malfunction of
the device by high temperature and humidity.
8. Handling of power code
• Do not entangle the power cord. This will cause overheating and possibly a fire.
• Do not bend or twist the power cord, or apply excessive tension to it. This may cause a fire
and electrical shock.
• Do not lay the power cord under a desk or chair, and do not allow it to be pinched in order to
prevent it from being damaged and to avoid a fire or electrical shock.
• Keep the power cord away from any heating equipment such as a room heater. The cord's
insulation may melt and cause a fire or electrical shock.
• If the power cord becomes damaged (wiring exposed, breakage, etc.), immediately turn off the
power at the rear of this unit and shut off the main supply power. Then contact your nearest
dealer for replacement of the power cord. Leaving it may cause a fire or electrical shock.
• Connect the power plug to the receptacl which is supplied appropriate power and voltage.

impact is given to the caster, and could give
the damage. In that case, move the
device by lifting at the step.
3. When the installation place is determined,
pull down the lever of the stopped for
caster, and lock them.
4. Drain Tap Check
• Check whether the drain tap is detached
or not.

Operation Method
Procedure of Operation
Read through the following procedure if the liquid to be trapped is water type.
Use the glass condenser set (optional accessory) for the acid or organic solvents. Refer to the
operation manual attached to the glass condenser for using this glass condenser.
Supply the power
ON
1. Turn "ON" the earth leakage breaker.

Operation of the refrigerator
2. Turn "ON" the refrigerator switch. The refrigerator
activates.
There is the case that the starting sound of the refrigerator
might become higher depending on the operation initial status
and ambient temperature. However, this phenomenon is not
abnormal.
2
Setting of cover with nozzle
1. Check whether there is a dent or dust on the trap packing
or cover with nozzle or not.
If any dent or dust is detected, the vacuum degree of the
inside of the trap bath becomes worse.
2. Mount the cover with nozzle on the trap packing as
checking the "IN" and "OUT" of the nozzle direction.
After setting the cover with nozzle, check the vacuum degree
of the sealing parts. Insufficient sealing could cause the air
leakage from the trap packing.
3
Vacuum hose connection
Connect the cover with nozzle with its "IN" side connected to
vacuum equipment and with its "OUT" side connected to the
vacuum pump using the vacuum hose.
There is "IN" and "OUT" side for the cover with nozzle. Do
not connect to inverse side.
The vacuum hose is not an attached accessory. Prepare it
by yourself. Apply the vacuum hose with the inner diameter
12mm or 15mm.
4
Operation of the vacuum pump Turn "ON" the vacuum pump. The vacuum pump collects
the steam from the vacuum equipment to the trap bath.
5
End of operation
1. Stop operating the device.
2. Remove the vacuum hose from the cover with nozzle.
3. Turn "OFF" the vacuum pump.
4. Melt the ice in the trap leaving in the natural temperature or
by pouring the hot water. After melted all ice, drain all the
water from the device by removing the drain tap.
NOTE) Be sure to turn "OFF" the vacuum pump switch after
turning back the pressure of the vacuum pump to normal
one for preventing from the inverse flow of the oil.

This unit is not designed as the explosion-proof construction. Pay special attention to the
handling of the sample to be handled with this unit on the consumption with the explosive
material, flammable material, and similar ones. The flammable material may be vaporized by
leaving it at the temperature higher than room temperature, and could cause the fire or
explosion. When handling such material, provide ventilation with enough before the operation.
(Refer to page22 “List of Dangerous Substances”.)
CAUTION!
Maximum trap capacity
The max. trap capacity for the water type liquid is around 0.9kg (CA300) or 0.8kg (CA800).
Inserting too much trap to this unit could cause the clogging of "IN", "OUT" nozzle.
Do not step on this unit
Do not step on this unit. It will cause injury if this unit fall down or break.
Do not put anything on this unit
Do not put anything on this unit. It will cause injury if fall.
During a thunder storm
During a thunderstorm, turn off the power key immediately, then turn off the circuit breaker and
the main power. If this procedure is not followed, fire or electrical shock may be caused.
Countermeasure for stop operation during night or long-term stop
In case of stopping operation during night or long-term, toggle the power switch to "OFF".
